Our take on the Monoprice 20W USB C Mini Cubic Wall Charger

A tiny single-port USB-C wall charger rated at 20W, about half the size of a standard 20W brick. It supports fast charging and folds into a travel-friendly cube, and it is ETL-certified. At $10.94 at Connection as of November 6, 2026, it sits at the low end of its recent price range, so this is a good moment to buy.
